Embedded Database for .net that can run off a network |

[SQLite][1] came to my mind while reading your question, and I'm quite sure that it's possible to access it from a network drive *if* you keep yourself to the constraint of 1 user at a time.

I think NUnit **is** your best bet. With TestDriven.NET, you get great integration within VS.NET. (Resharper also has a unit test runner if you're using it). NUnit it simple to use and follows an established paradigm. You'll also find plenty of projects/tutorials/guides using it which always helps.

Depending on which sub directory of All Users you want, there's a couple different options [defined here][1]. For "All Users/Application Data" you would use

Probably nothing in your example. My understanding is that "javascript:" is for anchor tags (in place of an actual href). You'd use it so that your script can execute when the user clicks the link, but without initiating a navigation back to the page (which a blank href coupled with an onclick will do).
For example:... |
I find this site helpful: <http://www.regular-expressions.info/>
Other than that, I use the corresponding documentation extensively and I believe, all said and done, there's no way around that. |
You can use the one built in, `hg view`. I believe you just have to enable it in your `.hgrc`. You'll also need tcl installed. I find it sometimes lags for a few seconds, but overall it's pretty decent. |
You can use the one "built in", [`hg view`][1]. You'll need `TCL` installed though.

I'm not clear exactly what you're asking, but variables will maintain their value for each iteration of a loop, as long as they're declared outside of the loop itself. For example:

rix0rrr's answer is correct. However, if you find yourself wanting to do something slightly more complicated, you can pass a function to the sort method telling it how to sort. For example,

CGI is great for low-traffic websites, but it has some performance problems for anything else. This is because every time a request comes in, the server starts the CGI application in its own process.

C# Include Derived Control in Toolbox |
|c#|visual-studio|winforms|textbox| |
This is in reference to my other question [Auto Clearing Textbox][1]. If I choose to derive a new TextBox control from TextBox instead of implement a user control just containing my Textbox, how would I include that in the toolbox.

Right-click the toolbox, click "Choose Items" from the context menu, browse to your DLL, and select it. |
OK, are you sure that is wise? I am picturing two scenarios here:
1. There is a default button on the form, which is "clicked" when enter is pushed".
2. There is no default button, and you want the user to have to press enter, regardless.
Both of these raise the same questions:

If you do take the rsync/filecopy approach with CVS, it is important to only sync the files at a time when there is not an active commit. Otherwise, the repository's lock file will get copied over and you will be unable to checkout/update on the target side until the next sync.
